Yes. For medical expenses to be deducted on the tax return, you
must itemize deductions on Schedule A, and your unreimbursed medical
expenses must exceed 10 percent of your adjusted gross income (AGI).
Then, you can only deduct the amount by which your unreimbursed medical expenses
exceed this 10 percent threshold (7.5% of AGI for age 65 and older until 2017).
However, some states allow the full deduction, even if you don't have
enough for your federal taxes.
Where do I enter my medical expenses?

"You can include in medical expenses amounts you pay to lose weight if it is a treatment for a specific disease diagnosed by a physician (such as obesity, hypertension, or heart disease). This includes fees you pay for membership in a weight reduction group as well as fees for attendance at periodic meetings. You can't include membership dues in a gym, health club, or spa as medical expenses, but you can include separate fees charged there for weight loss activities.
You can't include the cost of diet food or beverages in medical expenses because the diet food and beverages substitute for what is normally consumed to satisfy nutritional needs. You can include the cost of special food in medical expenses only if:
The food doesn't satisfy normal nutritional needs,
The food alleviates or treats an illness, and
The need for the food is substantiated by a physician.
The amount you can include in medical expenses is limited to the amount by which the cost of the special food exceeds the cost of a normal diet. "
